Pelargonium plant named ‘Dueimpres’

ABSTRACT

A new and distinct cultivar of Zonal  Geranium  plant named ‘Dueimpres’, characterized by its compact, upright to outwardly spreading plant habit; freely basal branching habit; dark green-colored leaves with zonation pattern; freely flowering habit; semi-double red purple-colored flowers; and good garden performance.

Botanical designation: Pelargonium zonale.

Cultivar denominaation: ‘Dueimpres’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of ZonalGeranium plant, botanically known as Pelargonium zonale, and hereinafterreferred to by the name ‘Dueimpres’.

The new Zonal Geranium plant is a product of a planned breeding programconducted by the Inventor in Rheinberg, Germany. The objective of thebreeding program is to create new compact Zonal Geranium plants withdark green-colored leaves and attractive flowers.

The new Zonal Geranium plant originated from a cross-pollination made bythe Inventor in July, 2005 in Rheinberg, Germany of a proprietaryselection of Pelargonium zonale identified as code number F-01-16, notpatented, as the female, or seed, parent with a proprietary selection ofPelargonium zonale identified as code number Z98-0276-003, not patented,as the male, or pollen, parent. The new Zonal Geranium plant wasdiscovered and selected by the Inventor as a single flowering plant fromwithin the progeny of the stated cross-pollination in a controlledgreenhouse environment in Rheinberg, Germany in May, 2008.

Asexual reproduction of the new Zonal Geranium plant by vegetativeterminal cuttings in a controlled greenhouse environment in Rheinberg,Germany since May, 2008, has shown that the unique features of this newZonal Geranium plant are stable and reproduced true to type insuccessive generations.

SUMMARY OF THE INVENTION

Plants of the new Zonal Geranium have not been observed under allpossible environmental conditions. The phenotype may vary somewhat withvariations in environment and cultural practices such as temperature andlight intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Dueimpres’. These characteristics incombination distinguish ‘Dueimpres’ as a new and distinct cultivar ofZonal Geranium:

-   -   1. Compact, upright to outwardly spreading plant habit.    -   2. Freely basal branching habit.    -   3. Dark green-colored leaves with zonation pattern.    -   4. Freely flowering habit.    -   5. Semi-double red purple-colored flowers.    -   6. Good garden performance.

Plants of the new Zonal Geranium differ primarily from plants of theparent selections in flower color.

Plants of the new Zonal Geranium can be compared to plants ofPelargonium zonale ‘Pacamia’, not patented. In side-by-side comparisonsconducted in Rheinberg, Germany, plants of the new Zonal Geraniumdiffered from plants of ‘Pacamia’ in the following characteristics:

-   -   1. Plants of the new Zonal Geranium were more compact than        plants of ‘Pacamia’.    -   2. Plants of the new Zonal Geranium had smaller leaves than        plants of ‘Pacamia’.    -   3. Flowers of plants of the new Zonal Geranium were more pink in        color than flowers of plants of ‘Pacamia’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Zonal Geranium plant, showing the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the photograph may differ slightly from the color values citedin the detailed botanical description which accurately describe thecolors of the new Zonal Geranium plant. The photograph comprises a sideperspective view of a typical flowering plant of ‘Dueimpres’ grown in acontainer.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations andmeasurements describe plants grown in 10.5-cm containers in Rheinberg,Germany in a glass-covered greenhouse during the summer and underconditions which closely approximate commercial production. During theproduction of the plants, day and night temperatures averaged 18° C. andlight levels averaged 4,500 lux. Plants were pinched one time threeweeks after planting. Plants had been growing for 13 weeks when thephotograph and the description were taken. In the detailed description,color references are made to The Royal Horticultural Society ColourChart, 1995 Edition, except where general terms of ordinary dictionarysignificance are used.
